Abstract

The article presents the results of field experiments to determine the thermal and technical and economic indicators of flat capacitive solar-water heating collectors made of translucent plastics with bottom absorption of solar radiation for seasonal use in the regions of the Republic of Uzbekistan. As follows from the results during the warm season, the seasonal thermal efficiency in the reservoirs under consideration, depending on the thickness of the water layer for the season, respectively, is 17% at 0.05 m and 24% at 0.07 m. At the same time, the specific savings for natural gas from the Shurtan deposit and Angren coal deposit are 488 Nm3 and 910 kg per season, respectively. The reduction of CO2 emissions during the season during the combustion of natural gas from the Shurtan deposit is 667 kg and Angren coal deposit (depending on the percentage of carbon in the composition of coal) from 3148 to 4814 kg of CO2, respectively.

季节性平板电容式太阳能集热器热工及技术经济指标
本文介绍了现场实验的结果,以确定乌兹别克斯坦共和国地区季节性使用的半透明塑料制成的底部吸收太阳辐射的平板电容式太阳能热水器的热性能、技术和经济指标。根据温暖季节的结果,根据季节水层厚度的不同,所考虑的水库的季节热效率在0.05米处分别为17%,在0.07米处为24%。同时,Shurtan矿床和Angren煤矿的天然气每季节的具体节约量分别为488 Nm3和910 kg。Shurtan矿床天然气燃烧期间的季节CO2排放量减少了667 kg,Angren煤矿(取决于煤炭成分中碳的百分比)的CO2排放量分别从3148 kg减少到4814 kg。
